Abstract
The present disclosure concerns a method for determining a mold shape quality (Q) of an ear mold (2) customized to an ear canal (31) of a user by means of a mold testing system (100). The mold testing system (100) comprises an acoustic generator (3) and a microphone (4) arranged in a test housing (1) with an open end (1c) that is connectable to an inner passage (2c) of the custom ear mold (2). The method comprises inserting the ear mold (2) into the ear canal (31); connecting the test housing (1) to the ear mold (2); generating an acoustic signal (Sg) into the ear canal (31) via the inner passage (2c); measuring the acoustic signal (Sr) from the ear canal (31); comparing the measured signal (Sm) with a reference signal (Se); and providing a feedback signal (Sf) based on the said comparison. The feedback signal (Sf) is a measure for the mold shape quality (Q) of the custom ear mold (2).
